"Finasteride is only safe for use by adult men in the treatment of male pattern baldness. Women and children must not take this medication, and pregnant women must avoid coming into contact with it." Dr Louisa Draper Finasteride is a common drug used in the treatment of hair loss or pattern baldness in men. Finasteride is the generic version of the active medicine used in Propecia, which works by decreasing the amount of the sex hormone DHT (dihydrotestosterone) in the male body. DHT is a hormone that can cause the hair follicles on your scalp to shrink, making it difficult for healthy hair to grow or regrow. By blocking the production of DHT in the body, finasteride helps normal hair growth to resume. Your hair loss should reduce or stop within three months of regular use. Finasteride is only safe for use by adult men in the treatment of male pattern baldness. It is an oral medication, taken once a day, and available on prescription. It is prescribed to stimulate hair growth in men with male pattern baldness. Propecia’s active ingredient is finasteride, and it was originally developed to treat a condition which causes enlarged prostate glands (benign prostatic hyperplasia). Finasteride works by reducing dihydrotestosterone (DHT) levels in the scalp. The hormone DHT contributes to male pattern baldness, and Propecia medication helps to reverse the hair loss process by decreasing the effect of DHT on the hair follicles. It takes around three months to see any results from using Propecia. It is recommended for men over the age of 18 only and must not be taken by women.
“But by age 60, about 80 percent of men and 40 percent of women will have a measurable amount of hair loss,” says Shilpi Khetarpal, M. The cause is usually genetic: male- and female-pattern hair loss. In men, hormones called androgens cause strands to fall out too early. In women, the action isn’t as clear, though androgens may play a role for some. Thyroid problems, stress, trauma, autoimmune disease, and nutrient deficiency can also cause hair loss. A 2016 review of six studies by the independent Cochrane Collaboration found that twice as many women who used minoxidil experienced at least moderate hair regrowth compared with those who used a placebo. Should you try one of the over-the counter or prescription products touted to help? You might see the following products on drugstore shelves and online: Topical minoxidil (Rogaine and generic): This OTC drug, applied to the scalp daily, stimulates hair follicles and pushes more hair into the growing phase. And a review published in 2017 in the Journal of the American Academy of Dermatology (AAD) found that men using the topical twice daily had an average increase of nearly 15 hairs per square centimeter (with 5 percent minoxidil) and eight hairs (with 2 percent minoxidil). A 2017 review of studies found little evidence that biotin offsets hair loss except in the rare instance of biotin deficiency. “Low-level lasers do stimulate hair growth, and the at-home devices available might be helpful in some cases,” says Elise A. D., director of the Hair Disorders Research and Treatment Center at the Duke University Medical Center in Durham, N. Some data supports their effectiveness, but none have been compared with topical minoxidil or finasteride. Supplements: Many dietary supplements are marketed for hair growth, most with high levels of the B vitamin biotin. Low-level laser or light therapy: These combs, caps, and headband devices are said to stimulate follicles. And they don’t undergo the same rigorous testing that medications do. Your doctor may prescribe an oral drug along with topical minoxidil. The AAD says it helps slow hair loss in most men and stimulates regrowth in many. “It won’t help regrow hair that’s been gone for three or more years,” Khetarpal says. Finasteride and dutasteride, both 5-alpha reductase inhibitors, are considered first-line treatment for androgenetic hair loss in men and used increasingly in women. In each case, patients are expected to take the medications indefinitely despite the lack of research regarding long-term adverse effects. Concerns regarding the adverse effects of these medications has led the United States National Institutes of Health to add a link for post-finasteride syndrome to its Genetic and Rare Disease Information Center. Herein, the authors report the results of a literature search reviewing adverse events of 5-alpha reductase inhibitors as they relate to prostate cancer, psychological effects, sexual health, and use in women. Several large studies found no increase in incidence of prostate cancer, a possible increase of high-grade cancer when detected, and no change in survival rate with 5-alpha reductase inhibitor use. Currently, there is no direct link between 5-alpha reductase inhibitor use and depression; however, several small studies have led to depression being listed as a side effect on the medication packaging. Sexual effects including erectile dysfunction and decreased libido and ejaculate were reported in as many as 3.4 to 15.8 percent of men.
Side effects of finasteride in women include, but are not limited to harm to a fetus finasteride can not be used in pregnancy, fatigue, weight gain, depression, anxiety, decreased libido, sexual dysfunction, hair shedding, breast tenderness, breast enlargement.
